Web Zurich presents inspiring talks all about the web. Join us for the Mai 2026 meetup! We will have three talks as well as chit-chat and drinks. Whatapp: [https://chat.whatsapp.com/FxOfVTK9nf431xHtVl3eGK](https://chat.whatsapp.com/FxOfVTK9nf431xHtVl3eGK) Website: [https://webzurich.ch](https://webzurich.ch) 18:30 \~ 19:00 Arrival time with drinks, chat 19:00 \~ 19:10 Welcome and introduction 19:10 \~ 19:30 *Alex Suzuki* **Monetizing JavaScript: Building Profitable Products as a Solo Developer** Lessons learned from building and launching a commercial JavaScript library as a solo developer. 19:30 \~ 19:50 *Hugo Sousa* **Ten times tea** I'm building a programming language. When I got to the frontend, I ran into a problem: React's mental model is elegant, but the mental model is at odds with the code. Hooks, effects, and render passes create a runtime that bears little resemblance to the code we write. The Elm programming language works differently and its architecture (TEA = The Elm Architecture) has been adopted by other tools over the years. So I copied it as well. My language embeds TEA at the language level, not as a library. This unlocks time-travel debugging, reproducible application state and serializable bug reports that include the entire program state. This talk covers the quick introduction of my language, TEA, why TEA is the right fit and what becomes possible when the architecture is baked into the language itself. 19:50 \~ 20:10 *Marco Gähler* **Software testing** Many old software projects don't have any tests - if the code works, why should you bother with tests? Well, you really should bother, because code changes all the time. During development, you keep adding new features which at times requires large scale modifications of the code that will inevitably alter existing functionality. And in existing projects, one still has to make updates once in a while, for example for security patches. These things will always break existing functionality and tests are the only remedy against this issue. In this talk, we will look at the basic idea of tests, how to implement them, what issues to look out for and how you can test pretty much any piece of code if your code base is well structured. 20:10 onward More drinks & chat We look forward to see you there!

CLICK HERE](https://atelier-yuniku.as.me/nerikomi-bowl) 🎟️✨ **MATCHA OR CEREAL NERIKOMI BOWL: Pottery Workshop** Pottery Workshop with Tereza (in English) at atelier yuniku 2 hours / CHF 60.00 Join us for a **calm session** where you’ll create your own **ceramic bowl** using the **nerikomi technique**. Whether you prefer a **matcha** or a bowl for your morning **cereal**, you’ll shape a piece that fits your style. You’ll begin by choosing your clay colors - earthy tones that are layered and combined to form soft, marbled patterns. Using the nerikomi technique, you’ll mix the clay to create natural color flows, then shape your bowl by hand using a pinching technique. To finish, you’ll gently carve and scrape the surface, revealing the patterns hidden within the clay. The result is a one-of-a-kind bowl with a raw, organic look. After the workshop, we’ll glaze and fire your piece for you. **Good to know:** * Course in English * Beginner-friendly – no prior experience needed * Choice of 2–3 clay colors * All materials provided * Small apéro with wine included * Bowl ready for pickup in approx. 4 weeks * One bowl included; extra bowls can be made for a materials fee **Check out more of our courses: [https://www.atelier-yuniku.ch/en/courses](https://www.atelier-yuniku.ch/en/courses)** ℹ️ Please note: * Tickets are non-refundable * Photos and videos may be taken during the event for communication and promotion purposes.

This is proven by data in [ANCIENT HISTORY](https://www.youtube.com/watch?v=Kg_47J6sy3A), in [MODERN HISTORY](https://www.kiltrohealth.com/blog/blue-zones-social-connection-the-secret-to-longevity-and-well-being) and also scientifically proven by [HARVARD ](https://www.youtube.com/watch?v=8KkKuTCFvzI)in an 87 year old study. Yes this makes you [HEALTHY](https://www.scientificamerican.com/article/relationships-boost-survival/#:~:text=Overall%252C%2520social%2520support%2520increases%2520survival,%252Da%252Dday%2520smoking%2520habit) and is what you really need - the other things are not as important as society tells you. . * **WHAT is Connection Space?** Imagine a co-working space where everyone is with headphones, laptops, mostly being 'alone' all day ... or a cafe/restaurant/bar where pretty much all people talk to people they already know.. . The **"Connection Space"** is exactly the opposite of that; its a **fun** social environment outside family and work, a cultural exchange, where we **unite** and hangout with **new and old friends** as **one community**. . Thats it. . No to phones, laptops, zoom-calls, books No to a specific reason to get together (eg. only for specific hobbies, genders, age groups, languages etc) No to just talking to your friends Not a dating, not a party, not an expat-only meetup NO to division (political racial gender etc) . Yes to simple and real in-person connection with new and old friends YES TO FUN! We got many optional activities for you to try out Yes to feeling like home & come as you are Yes to unity, love and respect for one another Yes to eating, drinking and music Yes to everyone-is-welcome & always-free events YES to UNITY! Getting along with each other in spite of different opinions . Our events are **inspired** by the Greek village culture of "[Καφενείο](https://en.wikipedia.org/wiki/Kafenio)" (village coffeeshops) with photos [HERE](https://www.google.com/search?sca_esv=569660528&sxsrf=AM9HkKlXnclaLfgcockKtdr9qHdmD5jaGw:1696060562834&q=greek+%CE%BA%CE%B1%CF%86%CE%B5%CE%BD%CE%B5%CE%B9%CE%BF&tbm=isch&source=lnms&sa=X&ved=2ahUKEwi52fX67dGBAxXnlf0HHZNiBHUQ0pQJegQICRAB&biw=1460&bih=913&dpr=2). When myself Christos was a kid, my granddad took me to these "[Καφενείο](https://en.wikipedia.org/wiki/Kafenio)". Every neighbourhood had one, and people met, without an exaggeration, on a daily-basis. It was the community center of the village. People met new and old friends, played games, socialised, ate snacks, drank coffee and ouzo. It was a very friendly, welcoming and homey environment. Unfortunately this concept is rapidly dying in Greece. As a kid I had extremely good memories of these coffeeshops, and for this reason I am passionate to revive and recreate this environment and also add a modern twist. Hope you enjoy it! . * **WHAT is NOT Connection Space? NOT** a drinks or party event (responsible drinking only, no shots, no free drinks). **NOT** a dating event. **NOT** foreigners-only, but everyone is welcome * **What KIND of event is this?** Its a mix of **social** and **cultural event** that build **community**. We have many people from so many different cultures socialising, we promote culture with events with Art exhibitions and Live Music and we also revive the social culture of the Greek traditional village coffeeshop (Καφενείο - read more above). * **WHO?** Wir wollen gerne mehr **Schweizer/innen** dabei haben! Alle sind willkommen und die meisten können Deutsch sprechen. Not an expat event. **Everyone welcome**! * **Mindful Connection Games:** from [The School of Life](https://www.theschooloflife.com/shop/?_product_type=games-card-sets) available: Confessions Game, The Friendship Game, Connection Game, The Loser Game, Games for grown-ups and three sets of "100 questions" (Conversation Toolkit & Careers & Relationships) * **Fun Social Games:** bring your own **board/card games** or choose from: Cards against humanity, Exploding Kittens, Codenames, Debatable, Sotally Tober, Taboo, Mafia, Uno, Monopoly and more. . Looking forward to **fun quality Connections**! 🙂
